Pass response to WSServerHandshakeError

[mattupstate]

It might be useful to be able to reference the response when capturing a WSServerHandshakeError. The response object also doesn't seem to get closed when the client consumes this error.

I believe you actually need status code and headers only, not the whole response.
See #706 for fix

Fixed by #706

@asvetlov can we re-open this issue ? since ws_connect actually makes troubleshooting connection errors very difficult as the response in our case contains detailed error information.

Please create a new one with detailed description of your problem.
